The search service can find package by either name (apache),
provides(webserver), absolute file names (/usr/bin/apache),
binaries (gprof) or shared libraries (libXm.so.2) in
standard path. It does not support multiple arguments yet...

The System and Arch are optional added filters, for example
System could be "redhat", "redhat-7.2", "mandrake" or "gnome",

RPM resource tmpwatch

The tmpwatch utility recursively searches through specified
directories and removes files which have not been accessed in a
specified period of time. Tmpwatch is normally used to clean up
directories which are used for temporarily holding files (for example,
/tmp). Tmpwatch ignores symlinks, won't switch filesystems and only
removes empty directories and regular files.
